To all whom it may. Be it known that I, GERALD Form, a subject of the King dent of the city of Winnipeg, in the Prove ince of Manitoba, Canada, have invented certain new and useful Improvements in At: Stoves, of which the following is the specification.

An object of the invention device readily attachable to I let of a gas stove which will collect and decooking fumes and easy is'to provide a also retard the escape of heat from the oven and thereby eifect a considerable saving of gas.

A further object of the invention is to construct the device in a simple, cheap and durable manner and so that it can be readily detached and opened for cleaning and renewing purposes.

With the above objects in view the invention consists essentially in the arrangement and construction of parts hereinafter niore particularly described and later pointed out in the appended claims, reference being bad to the accompanying drawing in which Fig. 1 is a perspective view of a gas stove with my device attached.

Fig. 2 is a plan view of the device. I

Fig. 3 is a vertical sectional view centrally through the device.

Fig. 4 is a view showing a modified con-- struction of the appliance.

In the drawing like characters of reference indicate corresponding parts in the. several figures.

I have found that inia great many instancs gas stoves are used without any pipe or flue connecting the oven witha chimney, and this results in the distributingin the room of disagreeable, greasy,

the; room 'wallsby posit of grease and suchlike. 3 Further, with and without flues,

amount of heat lost, such escaping out the flue outlet and this resultsin adirect loss in gas to maintain the oven at the proper cook-' ing temperature. 1

The device which I have invented obviates the above mentioned troubles and can beutilized to advantage with or without a flue or outlet pipe. I

Referring to the drawing, wherein the de vice is shown, it will be observed that it comcasing or body part 1 adapted of Great Britain, and a resithe oven out cooking and gasfulges .1

there is a considerable to fitover the collar 2 leading from the oven of the stove 3, the said casing being preferably made from stove'piping and expanded at the lower :end to-ensure of easy attachment. Centrally of its length the casing is provided with a circumscribing rib 4 which supports an open wire grid5,-1nserted from the top and dividing the interior of the casmg mto anupper compartment 6 and a low- .er'compartment7.

e upperend of the casing is closed by a removable top or cap 8 which perforated at 9 to allowthe purifiedvapors .to escape.

In the upper compartment, and resting on the grid I place a quantity of steel wool 10, immediately above whichI put a layer of combed asbestos 11', the two-materials practlcally filling the chamber. A cake of'black carbon l2 rests onthe asbestos. and; acts as a complete deodorizer.

' g ere no flue pipe used the-device is attached directly to the oven outlet collar2 as bestshown in Fig. 10f the draw The oven es, gas and vapors are bro en up and distributed by the steel wool and the mois ture, ass and such like are absorbed by the asfis tos. The remaininggas and fumes are deodo'rized' by the carbon. It is also'to be noted that the asbestos and steel wool have the effect of retarding the escape of heat from the oven by way of the outlet collar. This eifects a considerable saving in the gas used bylthe Stove. l I
